Add a gamma algorithm for the rkisp1. It defaults to a gamma of 2.2 which
closely resembles sRGB. No seperate sRGB mode was implemented because the pwl
that models the gamma curve is so coarse that there is basically no difference
between srgb and gamma=2.2. The default can be overridden within the tuning
file or set at runtime using the gamma control.
The gamma algorithm is not enabled by default. This will be done in future
tuning file updates.

std::unordered_map::merge(source) has the side effect of actually moving items
from source to target. In this case the controls were removed from the source
maps on the first call to updateControls() and on the second call to
updateControls() they were missing in the source maps and therefore also
removed from the camera. Fix this by using insert() instead of merge(). This is
most likely cheaper than copy-contructing the source map.

A camera gamma of roughly 2.2 is necessary to produce correct output
images on a standard monitor. Add a control for that.

There was an issue where using map to store the test cases meant that
the test for ignoring unused bits was skipped because of clashing keys.
Fix this by moving the offending test out of the loop.
While at it, also change the arbitrary floating comparison precision to
be more precise.
Also fix a missing documentation brief.

Allow the DmaBufAllocator used by the software ISP to use memfd() +
/dev/udmabuf for the software ISP destination buffers.
This is useful on Linux distributions where normal users are not allowed
to access /dev/dma_heap/* while they are allowed to access /dev/udmabuf.

The dma-buf allocator currently allocates from CMA and system heaps.
Extend the dma-buf allocator to support allocating dma-buffers by creating
memfd-s and turning those into dma-buffers using /dev/udmabuf.
The buffers allocated through memfd/udmabuf are not suitable for zero-copy
buffer sharing with other devices.

Users of the DmaHeap class really just want some way to allocate
dma-buffers from userspace. This can also be done by using /dev/udmabuf
instead of using /dev/dma_heap/*.
Rename DmaHeap class to DmaBufAllocator in preparation of adding
/dev/udmabuf support.
And update the DmaHeap class docs to match including replacing references
to "dma-heap type" with "dma-buf provider".
This is a pure automated rename on the code ('s/DmaHeap/DmaBufAllocator/')
+ file renames + doc updates. There are no functional changes.
The DmaBufAllocator objects in vc4.cpp and software_isp.cpp are left named
dmaHeap_ to keep the changes to those 2 files to a minimum.

Update to the new API, while preserving backward compatibility to ease

upstream kernel yet, users of the API need kernel patches, and are

The fence test is racy, as it relies on the main loop being executed
between completion of request signalledRequestId_ and
signalledRequestId_ + 1. This usually happens, but is not guaranteed.
To fix the race condition, change the request identification logic by
replacing usage of the cookie value, which is zero-based and wraps
around at nbuffers_ - 1, with a completed request counter that is
one-based and doesn't wrap. The completedRequestId_, expiredRequestId_
and signalledRequestId_ variables now track the identifier of the last
request that has completed, the request whose fence will time out, and
the request whose fence will be signalled.

TODO #4 was recorded at a time where the IPA module computed gain values
and the ISP computed the look up tables. The gains were higher-level
parameters. Now that the look up tables are computed in the IPA module,
the IPA and ISP are more tightly coupled and the TODO item is less
relevant.
Let's drop the TODO item. We may or may not need to switch to a
different representation in future but there is currently no good need
for this and the conversion of the values would be just waste of CPU
cycles.

Constructing the color mapping tables is related to stats rather than
debayering, where they are applied. Let's move the corresponding code
to stats processing.
The same applies to the auxiliary gamma table. As the gamma value is
currently fixed and used in a single place, with the temporary exception
mentioned below, there is no need to share it anywhere anymore.
It's necessary to initialize SoftwareIsp::debayerParams_ to default
values. These initial values are used for the first two frames, before
they are changed based on determined stats. To avoid sharing the gamma
value constant in artificial ways, we use 0.5 directly in the
initialization. This all is not a particularly elegant thing to do,
such a code belongs conceptually to the similar code in stats
processing, but doing better is left for larger refactoring.
This is a preliminary step towards building this functionality on top of
libipa/algorithm.h, which should follow.

The white balance computation didn't consider black level. This is
wrong because then the computed ratios are off when they are computed
from the whole brightness range rather than the sensor range.
This patch adjusts white balance computation for the black level. There
is no need to change white balance application in debayering as this is
already applied after black level correction.
Exposure computation already subtracts black level, no changes are
needed there.

Add support for the following HDR modes in the Raspberry Pi IPA:
- Night mode
- Single exposure mode
- Multi-exposure (merged and unmerged)
The algorithm is updated to expect the HDR short channel to meter
explicitly for highlights. This means that it will not in general
under-expose the short channel more than is actually necessary.
When images don't have much saturation, it's good to detect this so
that some of the boost we want to apply to the dark areas can be
implemented as regular gain. This means we can then adjust the tone
curve less, leading to less flat looking images.
The impact on the HDR algorithm is then that this determines how we
build tonemaps dynamically. The highlights are more-or-less correct
now, so we have to build a power-type curve that gives us the
appropriately configured targets in the lower part of the histogram.
We allow the tuning file to supply the maximum spatial gain value,
rather than the whole curve (though it can supply this if it
wants). Some parameter defaults are tweaked to be generally better
across the range of our cameras.

To match the enumerated media devices, each registered pipeline handler
is used in no specific order. It is a limitation when several pipelines
can match the devices, and user has to select a specific pipeline.
For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is
created to give the option to define an ordered list of pipelines to
match on.
LIBCAMERA_PIPELINES_MATCH_LIST="<name1>[,<name2>[,<name3>...]]]"
Example:
LIBCAMERA_PIPELINES_MATCH_LIST="rkisp1,simple"

The PipelineHandlerFactoryBase class has a name that is propagated to
the PipelineHandler instance it creates.
In present implementation, this name comes from the
REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the
stringified name of the PipelineHandler derived class. Therefore,
PipelineHandler factories and instances names can be quite long such as
"PipelineHandlerRkISP1".
A libcamera user may have to explicitly refer to a PipelineHandler name
for configuration purpose: one usage of the name can be to define a
pipeline handlers match list and their priorities. It is desired, for
user convenience, to use a short name to designate a pipeline handler.
Reusing the short pipeline names already defined in the meson option
files is an existing and consistent way of naming pipelines.
This change adds an explicit name parameter to the
REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to
define the name of a pipeline handler factory, instead of the current
pipeline handler class name.
Each pipeline registration is updated accordingly. The short name
assigned corresponds to the pipeline directory name in the source tree.
It is consistent with pipelines names used in meson.
Changing the pipeline name has an impact on the IPA modules: each module
defines a IPAModuleInfo structure. This structure has a pipelineName
member defining the pipeline handler name it shall match with.
Therefore, each internal IPA module definition has to be changed to have
its IPAModuleInfo pipelineName name updated with the short pipeline
handler name.
In addition to this pipelineName member, the IPAModuleInfo structure
also has a name member, associated to the IPA module name. Having
renamed the pipelines to a short name, the pipeline name and the IPA
module names of the IPAModuleInfo structure are the same: for in-tree
IPA, they correspond to the respective pipeline and IPA subdirectories
in the source tree. However the IPA name could be different, for
instance with a close source IPA implementation built out-of-tree. Thus,
it makes sense to keep the IPA name in that structure, as the 2
definitions may not always be redundant.

The camera name is copied in gst_libcamera_src_open() as we can't hold
the lock protecting the name while calling GST_ELEMENT_ERROR(). The
GST_ELEMENT_ERROR() macro sends a message on the bus, taking more locks
and possibly causing issues.
However, the current code makes the copy, but does not actually use it.
So fix that.

A new Doxygen warning introduced in a recent commit went unnoticed, both
in manual tests and in CI. Unlike C/C++ warnings that are treated as
errors, we don't fail the build with Doxygen warnings. This is due to
the fact that the libcamera documentation compiles cleanly only with quite
recent versions of Doxygen. Enabling the WARN_AS_ERROR Doxygen option
unconditionally could bother many users.
To improve the situation, add a meson option to treat Doxygen warnings
as errors. The option is disabled by default, preserving the current
behaviour, and will be enabled in CI builds.
